15.1
When configuring and using the ADC the following
functions must be considered:
• Port configuration
• Channel selection
• ADC voltage reference selection
• ADC conversion clock source
• Interrupt control
• Result formatting
15.1.1
The ADC can be used to convert both analog and
digital signals. When converting analog signals, the I/O
pin should be configured for analog by setting the
associated
Section 11.0 “I/O Ports” for more information.
15.1.2
There are 14 channel selections available:
• AN<11:0> pins
• Temperature Indicator
• FVR (Fixed Voltage Reference) Output
Refer to Section 13.0 “Fixed Voltage Reference (FVR)”
and Section 14.0 “Temperature Indicator Module” for
more information on these channel selections.
The CHS bits of the ADCON0 register determine which
channel is connected to the sample and hold circuit.
When changing channels, a delay is required before
starting the next conversion. Refer to Section 15.2
“ADC Operation” for more information.
15.1.3
The ADPREF bits of the ADCON1 register provides
control of the positive voltage reference. The positive
voltage reference can be:
• V
• V
• FVR 2.048V
• FVR 4.096V (Not available on LF devices)
See Section 13.0 “Fixed Voltage Reference (FVR)”
for more details on the Fixed Voltage Reference.
